Garrya

Botanical

What is it

Garrya (Garrya elliptica), also called silk tassel bush, is a shrub native to the western United States. The bark and leaves are used in some traditional and homeopathic preparations, particularly for menstrual support.

How it works

Garrya elliptica contains diterpenoid alkaloids including garryine and garryfoline, which have been studied for muscle-relaxant and uterine activity in preclinical work. Traditional use focuses on menstrual cramping and similar smooth muscle complaints. Human clinical evidence is essentially absent. Most modern use is via homeopathic dilutions rather than full-strength herbal extracts.

Interactions

Theoretical interactions with antihypertensive and muscle-relaxant medications. Limited formal interaction data.
